This chart shows how tariff rates vary within each HS chapter across different products. Each violin shape uses Kernel Density Estimation (KDE)—a statistical method that smooths individual data points into a continuous distribution curve. The width at any height shows the density (concentration) of products with that tariff rate. A wider section means more products have tariffs in that range. The box plot inside shows quartiles: the middle line is the median, the box spans the 25th to 75th percentiles, and the white line is the mean.
Chapters like textiles show narrow, high-positioned violins—meaning nearly all textile products face uniformly high tariffs (6-15%). Machinery chapters show wide violins spanning 0-25%, indicating some machinery enters duty-free while other items face high tariffs. The KDE smoothing reveals these patterns more clearly than raw histograms would.
